Narrative:

During a training flight for the purpose of NAVAID training; my post solo private pilot student; myself; a CFI; and a backseat observing private pilot license student were east of lmo at 7;100 feet. I had made two position reports on CTAF when the student pilot noticed a canadian registered mooney immediately ahead and to our left. I prompted the student to make an easterly descending turn as the plane overflew us by less than one wingspan width; and with our wingtips overlapping at approximately five knots over our airspeed (which is significantly slower than a mooney's normal cruising speed.) mid air impact was never imminent; but it was truly a 'near miss.' it was never apparent the [pilot of the] other aircraft saw our C172. The mooney continued northbound.
